ADJUSTABLE THREAD-GUIDE.

the said thread is to be marketed; our-immediate'object'being'to provide an improved form," and construction, of guide which-will be more serviceable than those now in common use, without being objectionably expensiveto produce.

In order to "explain our said invention clearlywe have provided the annexed drawings,in which Figuresl and 2 are respectively, side and plan views of a'thread guide embodying "our present improvements and Fig. ,3 is an elevation of the samewith the front' plate removed'to disclose the position of the guide disk, as well as the relative position of the guide channel member 16. Fig 4" is a plan View. of the device-of Figs. 1 and2 with'the saidguide channel member removed in order to show more. clearly the manner of locatin'gand clamping the guide disk'bet ween the side-plates:

Fig. .5 is a side .view of theguide disk and of the ."guideachannetmember, and in the Figl"6', wehave showng-relatively enlarged, an. edge view ofvthe guidedisk fonthepurpose of illustrating in the circumferential.

edge portion of said disk, the annular groove which serves to guide the thread as it is being rapidly laid upon the spool and also the adjacent parallel grooves which, meanwhile, iron down, so to speak, the coils of thread last laid upon the spool, as we will explain more in detail later.

In Figs. 7 and 8 we have illustrated, by side and top views, a slightly modified and simplified form of adjustable thread guide. Fig. 9 is a transverse section on line 9-9 of Fig. 7.

Briefly described, ourimproved guide consists of a forked holder having adjustably clamped therein a guide'disk formed with an annular groove, and in concentric relation thereto, a relatively adjustable guide Specification of Letters Patent. 7

memberformed as a segment of an -exte-' riorly channeled annulus.-

Referring to the annexed drawings, -the numeral 10 indicates the frame or holder of our improved guide, the samebeing, by pref- Patented'0c-t.15 1918. Applicationfi1ediDecember'27, '1915,*Seria1'No. 68,616.. Renewed 'February-26;19 18.- -Serial No..219;542

erence, formed oftwo-sectionswof wsteel punched and swaged to the desired form'and ,Welded, or otherwise fixedly 'secured, to

gether, one end portion of each half section being-bent out-ward to provide *sp'ace-in which may be located a disk 11 Whichis boredcent-rally and is clampedfixedly in the bifurcated-end portion of the' holder'10 by meansof ascrew or bolt 12.

As stated above, the disk 11 is formed with an annular groovewhich is denoted byfthe numeral 13 (see-Fig. 6); said groove-being located in the middle of the circumferential face of the disk and'between' a-plurality'of similar grooves 14 and 15. l

' Located in concentric relation to the described disk 11 is an exteriorly channeled Fig. 7 of the drawings, or maybe clamped by means of special screws 17 as illustrated in Figs. .1 and'2.

When in service our described guide is located with respect to the spool, uponewhich' Figs. 1 and 2, that is, to say the perimeter of the spool body, or the last coil of thread laid channel in the annulus 16, thence downward between the spool and the grooved disk 11 and thence around the spool as indicated by dotted line in Fig. 3 of the drawings, the bottom of the channel in the annular segment being exactly in line with the central groove 13 in disk 11 and being backed 01f, so to speak, as seen in Fig. 3, so that, in effect, the channel in the segment 16 leads the thread into the said groove 13 which holds the thread against lateral deflection, or displacement, while the complete guide travels forth and back along the spool, in the customary manner, and thus lays the thread upon the spool in successive coils with absolute regularity and under a uniform tension.

While the thread is thus being properly and positively guided to coil it upon the the thread is being wound, about as seen in spool, the grooves I L-15 at the sides of the central, or guide, slot 13 engage the coils of thread last laid with'a tendency to smoothf down, with a manglin and polishing effect,

the said coils of threa last laid.

I position, thus providing, with practically no delay and with no expense, a new guide slot 13 7 In practice wefind that the guide disk 11 may be adjusted to new positions of effectiveness about ten times before the entire groove 13 becomes worn and no longer useful, thus enabling our described guide to be used at least ten times as long as the ordinary forms of grooved guides in which no provision is made for adjustment of such guides to new (that is to say, unused) positions. With equal facility the channeled segment 16 may be adjusted in a curved path around, or upon, the disk 11, by easing back the central clamping screw 12, or the special clamping screws 17 as the case may be.

Referring now to Fig. 6 it will be seen that the circumferential edge portions of disk 11 are reduced slightly in diameter and chamfered as at 18, this construction being specially provided for an important purpose, to wit, to prevent the said disk from cutting into, or otherwise defacing, or injuring, the diagonal end walls of the spool as the guide travels from end to end of said spool and contacts with the spool; the described construction of the disk at 18 being such that said disk will readily ride upward along the said diagonal walls of the spool instead of defacing or marking said walls.

vIn effect, the channeled segment 16 serves to direct the thread to the groove 13 in disk 11 and the said disk serves to guide the thread and lay it in even coils upon the spool and, at the same time, the side grooves 14. 15 serve to iron down the coils previously laid by groove 13.

In the form of holder 10 illustrated in Figs. 7 and 8, the two portions are of the same design so that they may be produced by onepunch and die and so that the segment 16 may be clamped between the forked end portion of said holder by the same screw 12 which is used to clamp the disk 11 in its operative position.

Our described device may be cheaply produced, it may be quickly adjusted and'we have demonstrated by repeated trials that it performs its work effectively andsatisfactorily. V

Having thus described our invention we, claim as new and Wish to secure'by Letters Patent 1. The improvement in thread guides which comprises a holder, a. circumferentially grooved guide disk rotatably mounted in said holder, and means for clamping the said disk in its adjusted position; said disk being formed with a central circumferential guide groove and with parallel side grooves.

2. The improvement in thread guides which comprises a holder, a guide disk rotatably mounted in said holder, and means for clamping, said disk in its operative position; said disk being formed with a circumferential guide groove and with chamfered edge portions. w I

3. The improvement in thread guides which comprises a holder, a circumferentially grooved guide disk mounted in said.

holder, a channeled segment concentric with the said disk, and means for clamping the said guide disk and segment in their operative positions. 7
